Hello, thank you for reaching out to the Microsoft Community. I'm here to help with your questions or issues.
The issue is visible in your screenshot.
You created a folder named AI_Project, but the folder you're viewing in File Explorer is named "AI project", lowercase p, space instead of underscore.
Windows isn't case-sensitive, but it is path-specific. You're in the wrong directory. You cloned into C:\AI_Project\Minecraft-AI, but you're looking at C:\AI project.
File Explorer and CMD aren't pointing to the same location. Open C:\AI_Project in File Explorer and you'll see the cloned repo.
